Digital impression

Digital impression

In the digital workflow of prosthetic and restorative dentistry, plaster models of the dental arches have been replaced by digital replicas called digital impressions (figure 1A). Currently, these replicas can be obtained directly from the patient's oral cavity using intraoral scanners, without the need for plaster replicas (figure 1B).

FIGURE 1. The digital impression and the process for obtaining it from the oral cavity. A, the digital impression. B, the process for obtaining the digital impression using an intraoral scanner.

However, according to research published in recent years, digital impressions obtained using intraoral scanners have certain shortcomings: lack of accuracy when they correspond to large areas, difficulties in assessing their accuracy in vivo, difficulties in obtaining them from edentulous patients, etc. Therefore, the aim of this research line is to provide a solution to these shortcomings.

The progress made to date in this research line has been disseminated through articles published in scientific journals. In addition, a doctoral thesis has been defended within this research line.
